The slot isn't essential. All that's needed is a half-height key to connect the 2 change-wheels. Out with the hack-saw and files.

The Boxford handbook "Know Your Lathe" will tell you how to use it. A rather poor copy is here

If you need to use sodium hydroxide solution on, say a vertical surface it can be mixed into wallpaper paste to form a goo that will stay in place better than liquid.

Thread: What lathe does this steady rest fit?

Posted by Lee Rogers on 06/10/2021 08:06:38:

Am I missing something here? As a steady it's orientated the wrong way, can't say I've ever seen one like it.

I wondered if there's a missing mounting plate with a matching dovetail which would give adjustment across the machine axis.

As it stands, the item won't accomodate a very wide range of diameters.

Thread: Hermes. A Company in Total Confusion!
05/10/2021 14:40:40

Commiserations, very annoying. I think a problem that you may face in pursuing Hermes is that you do not have a legal contract with them The seller of the watch does. If the seller is bona-fide can he take this up with Hermes? I thought that all goods dispatched via Hermes had an automatic minimum insured value of around £20.

If you paid by, say, Paypal then their Buyer Protection might help.

+1 for the OP painting the ceiling and walls white. A good coat of emulsion would make a big improvement to overall light levels

Then install LEDs.

Hi Steve, re headstock alignment; all along I've been thinking that your Zyto would have the headstock cast integral with the bed. After looking at some photos, I now think that it might be a separate casting bolted onto the bed. Is that the case? If so then I think misalignment there could be at the root of your problem. Are there any alignment dowels in this joint. Before lashing out on a test -bar I'd try a quick and dirty check with a length of reasonably accurate bar held in the chuck and tested by traversing your dial gauge against it, ( but I'm a cheapskate). Check at several points of spindle rotation to even out run-out.

Even a length of bright mid steel would do for a start. Ground silver steel even better. Doesn't have to be too large a diameter.

If your problem does lie there then a test bar might be worth considering.

02/10/2021 21:45:30

Steve, levelling along the length of the lathe bed is of no real consequence. Across the bed should give identical readings at either end, but I doubt if your level is sensitive enough to really set the lathe up well.

The real test is to take a very light cut along, say, 2-3" of bar held in the chuck and shim the lathe feet to give parallel turning. A tedious job but light lathes have surprisingly flexible beds. Thr bench should be sturdy of course.

02/10/2021 21:12:42

Surely that's not the way to use a level, even if it's a good one? It should be across the ways

I'd advise Steve to set his lathe up to turn parallel by adjusting the mounting feet. Then adjust thr tailstock after that.

Also agree with above. The dial indicator might well not be showing anything useful.

Thread: Grinding tool bits
01/10/2021 14:00:46

10mm sq. HSS is OTT for most jobs on a Zyto and grinding that sized stuff on a typical hobby grinder is a tedious job.

6mm. is perfectly adequate for most work, considerably cheaper and much quicker to grind to shape.

They can be mounted in a 4-way toolpost or in a home-made holder with built-in top rake.


Thread: Boxford model c?
30/09/2021 09:00:38

Hi Robin,

Based on my Boxford the large double pulley has a grub screw and a keyway. The 4-step pulley has only a grub screw.

Both grub-screws tend to loosen and when this happens on the 4-step pulley you could well see the movement you describe. I haven't stripped mine down in years but IIRC this grub-screw bears on a flat on the shaft, hence a small amount of loosening gives quite a lot of angular movement.

Incidentally, there are 2 types of rear drive countershaft, basically as diagram G above. They're similar to one another but the later one is more compact but gives an overall higher speed range.

Thread: Chatter/finish problem
29/09/2021 16:52:34
Posted by Russell Eberhardt on 29/09/2021 16:38:28:

The bronze (not brass) bush in the headstock is split for adjustment. The grub screw is to stop it rotating and shouldn't compress the bush. The casting the into which the bush is fitted is also split so tightening the hex headed bolt will compress the bush to take up slight wear. I would imagine that there should be a stack of shims in the slot in that casting to control how far the compression goes. Thet would allow the bolt to be done up tight without locking the spindle.

Have you seen the section on Zyto lathes on ?


My first lathe, a Grayson had similar bearings to the Zyto, a split bush in a split housing tightened by a bolt. I think that arrangement was quite common with older, low-cost machines. There were no shims in my lathe. I understand that cracked bearing housings were not unknown if care wasn't taken.

I suspect that the OP's poor finish is largely due either to the grinding of the tool, with the small flat on the tip, or possibly, and less likely, to bearings worn badly out-of-round.

Thread: Turning (approximating) a Domed Surface
27/09/2021 18:48:11

I made this cover recently with the hand-graver I described. Pretty much free-hand and took only a few minutes.

A bit more care perhaps if 2 identical domes were wanted.

Brass in this case, but CI would be much the same.p1020919.jpg

27/09/2021 17:50:43

I would do that type of turning with a hand-held graver. Mine is a length of 1/4" sq. hss mounted in a file handle. A hand-turning rest is required. Mine is usually a piece of square or rectangular BMS suitably positioned in the tool-post.

The graver is sharpened by grinding its end-face flat at about 45 deg.

Works very well on most materials.

Anyone else built one of these. A class D amplifier with a claimed 10 W output from the early 1960s. You were lucky to get 2 W out of it and it produced copious amounts of TV and radio inteference:

Sinclair X10

I purchased an X10 when they were introduced. The price was about a £fiver. I don't remember it being available as a kit. My main recollection was that the performance was poor with very obvious audio distortion. When it came to the end of its fairly short life it was "dissected" at my workplace. The transistors all proved very much out of spec. Probably manufacturers' rejects. In those days Sinclair clearly built his equipment using the cheapest components that he could source.

Thread: Recommended Vice for Double Swivel Milling Slide
15/09/2021 09:32:30

Noting this, and your follow-up post, John …

Does anyone know whether Myford has changed the spacing of its Tee-slots ?

  • Chronos states Mounting Studs 30 mm between centres
  • Myford seems silent on the matter

Just wondering


I have an elderly Myford vice, identified as an MA71, seemingly similar to the ones currently sold by Myford as their original small vice, but now in a choice of colours, and each with a different reference no.

The hold-down slots are 1 9/16" (1.562" ) apart which think is, or was, Myford tee-slot spacing.

My vice has been useful over the years, but there may now be better ones on the market.

The camera is a Panasonic TZ3, it has given no problems until Win 10. As SOD says it may well be a driver problem.

Clive,my camera is a Panasonic TZ20, about 10 years old. Image file transfer to my Win10 PC via the USB cable that came with the camera is straighforward either by drag and drop or copy and paste.

Ditto if I move the SD card from the camera to the PC card reader slot.

If your USB cable link is not working, maybe due to its built in software / driver, have you tried moving the SD card thus avoiding this possible issue altogether?

Thread: Multimeter recommendations

My goodness! Buying "quality" to ensure reliability costs. RS will sell you a Fluke for no less than £459. or £500+ with a certificate No thank-you, but perhaps that's what the OP wants.

Can't remember when I bought my sub £10 cheapie, but more than 20 years ago I guess. I could buy 50 more for less than the cost of one Fluke. Those would last me to beyond 3021 AD.
